Title: Pivot-coupling device
Inventor: BOEDIGHEIMER REIMUND
IPC: B60J7/047
Filed: 1993-03-15
Abstract: Pivot-coupling device for the pivotable connection of two components (panel 2, deploying lever 1), of which one component (panel 2) has a supporting journal (3) and the other component (deploying lever 1) has a journal socket. Until the supporting journal (3) has engaged in the journal socket one component (deploying lever 1) can be adjusted approximately rectilinearly with respect to the other component (panel 2), and when the supporting journal (3) engages in the journal socket one component (deploying lever 1) can be pivoted with respect to the other component (panel 2) in a pivoting-angle region around the axis (6) of the supporting journal (3). The supporting journal (3) can be adjusted axially on the associated component (panel 2) between a coupled position and an uncoupled position. When the journal socket approaches relative to the supporting journal (3) a locking and release mechanism moves the latter, if necessary, out of the adjustment path of the component concerned (deploying lever 1) and when the supporting journal (3) is located in front of the journal socket, moves the journal into the socket. <IMAGE>

Patent DE-4314952-A1 (DE)
Inventor: LEIMBACH LUTZ DIPL ING
IPC: F16H63/42
Filed: 1993-05-06
Abstract: A gear position detector employs digital switches 7 - 9, eg a micro switch etc, to sense the plane 17, 18 of a gear lever in a H layout, and the gear engaging direction of the gear lever in the plane is detected by an analogue sensor 13, eg rotary angle sensor, as greater accuracy is required for automotive clutch actuation. Switches 7 - 9 are axially spaced in module 4, mounted on gearbox housing 2, and are activated by cam 6 when selector shaft 1 is moved in the direction of arrow B. In order to engage a gear the shaft 1 is rotated in the direction of arrow A, this rotation results in the slotted shaft 15 being rotated, as it is keyed for rotation with sensor 13, but is axially moveable relative to it, any movement results in a signal. Signals from switches 7 - 9 and sensor 13 are fed to a microprocessor having a learning program. A displacement sensor (14, fig 2) may replace sensor 13 and switches 7 - 9 may be arranged circumferentially (10 - 12, fig 2). <IMAGE>

Title: Process for producing a magnetic recording carrier
Inventor: RIEGER SIEGFRIED
IPC: B05D1/26
Filed: 1993-05-17
Abstract: It has been found that streaking in the coating of a flexible substrate in tape form by a magnetic dispersion caused by caking on the upper or lower lip of extruder gaps can be reliably avoided if a saturated solvent/inert gas mixture is fed into the clearances before and/or after the coating point. This is accomplished by introducing with apportioned pressure an inert gas into a vessel containing solvent and by controlling the temperature of the vessel such that it lies slightly below the pouring temperature, so that a risk of oversaturation of the inert-gas/solvent mixture is avoided (Figure). <IMAGE>

Title: Apparatus for conveying cylindrical workpieces
Inventor: LANGER BERND
IPC: B65G15/10
Filed: 1993-05-28
Abstract: The problem on which the invention is based is to provide a simple conveying apparatus which works on a principle, of which the effect to be utilised is independent, within wide limits, of the said parameters of the workpieces to be conveyed, is adjustable in terms of its conveying capacity in an uncomplicated way by a change of the conveying width and/or conveying speed and includes separation and alignment. According to the invention, each track of the conveying apparatus is formed by two belts which rotate at the same speed and which are guided on a web extending in the conveying direction. The webs are arranged next to one another with interspaces, in the initial part of the conveying stage these interspaces being closed by prisms which, in their cross-section, project above the belts and in this part form a dumping surface for the workpieces. The sector of use of the invention is the separation, alignment and conveyance of cylindrical workpieces, such as, for example, compression springs, from a heap to an appropriate processing unit. <IMAGE>

Abstract: Known valves for the injection of fuel or of a fuel/gas mixture have perforated bodies comprising two interconnected silicon plates, the upper plate having one or more injection openings and the lower plate being provided with a through hole through which a fuel jet can emerge. The new valve for the injection of fuel or of a fuel/gas mixture has a perforated body (22) which comprises an upper plate (24) and at least one, downstream, lower plate (25), in which a jet divider (70) is inserted. The jet divider (70) divides the through hole into at least two passage openings (72), producing or maintaining twin-jet flow in the valve. Passages (28) via which the gas impinges upon the fuel dispensed through an injection opening (60) are formed between the upper plate (24) and the lower plate (25), the number of passages being, for example, two.
